Sprocket / Gear Hub 1-1/4" bore.
All hubs are CNC machined from billet 6061-T6 aluminum alloy and have 6 (1/4-28) threads on a 5-1/4" bolt circle pattern. These hub are higher strength than most hubs on the market and will work great for SA, Outlaw and Open style racing. Yet are still light enough for Stock and Plate racing. Will work with traditional 35 pitch chain or 428 pitch chain.
